Chopart joint injury: a study of outcome and morbidity

Injuries involving the Chopart joint complex are relatively rare and frequently missed or misdiagnosed, often leading to a poor functional outcome. This study was performed to determine the outcome and morbidity in patients with Chopart joint injuries, and to increase awareness of this severe injury. Patients with a Chopart dislocation or fracture-dislocation, treated between January 2004 and January 2010, were identified using the appropriate diagnosis code and reviewing all radiographs of patients diagnosed with hindfoot or midfoot injuries treated at our institution. Data on patient characteristics, trauma mechanism, delay, and treatment were collected using patient files, operation reports, and by reviewing radiographs. Outcome was determined using the American Orthopaedic Foot & Ankle Society midfoot score and a visual analog scale satisfaction score, in patients with a minimum follow-up of 6 months. Nine patients (1.5 per year) were identified, including 6 women. The mean patient age was 41.6 ± 25.1 years. The trauma mechanism was sprain or sports injury in 5 (55.6%), motor vehicle accident in 3 (33.33%), and a fall from height in 1 (11.11%) case. Seven patients with an average follow-up of 31.3 ± 19.2 months reported a mean American Orthopaedic Foot & Ankle Society midfoot score of 72 (range, 32-100) points and a mean visual analog scale score of 7.1 (range, 5-10). Four (57.14%) patients still experienced pain or had limitations in daily activities at the time of the final follow-up. This study supports the conclusion of previous studies, which stated that a higher level of awareness is needed to prevent permanent disability.

Reconstruction After Malunited Lisfranc Injuries

Symptomatic secondary osteoarthritis of the Lisfranc joints due to malunion following Lisfranc joint fracture dislocations or ligamentous lesions at the Lisfranc and innominate joint level generally lead to a painful functional loss and a substantial disturbance of the walking performance. Initially missed or inadequately addressed primary lesions still represent the major source of Lisfranc joint malunions. Neuro-osteoarthropathic disorders may also become manifest in the Lisfranc joint region and may be mistaken for truly posttraumatic consequences. Secondary osteoarthritis may be combined with typical multiplanar deformities. The concept of a corrective arthrodesis includes restoration of stable physiologic axes and length proportions of the foot columns. A standardized approach to analyze the clinical picture and corresponding pathomorphology and the transfer into a comprehensive surgical concept which respects the realignment of any component of deformity is a prerequisite for a good functional outcome and a high degree of patient satisfaction. A fusion limited to the medial three rays combined with a soft tissue release may be sufficient for a favorable outcome in the majority of cases and preserve the mobility of the two lateral rays.
